Technical field

The utility model belongs to LED drive system technical field, is specifically related to the colored network controller that drives of a kind of LED.

Background technology

LED is a kind of light emitting semiconductor device that can electric energy be changed into luminous energy, belongs to solid state light emitter.The LED advantage is numerous, and, energy consumption long except the life-span was low, it was very convenient to control, as long as the just arbitrarily light modulation of adjustment electric current belongs to typical green illumination light source.Along with succeeding in developing of large power white light LED, LED is able to apply at lighting field, makes lighting technology face a new revolution.With regard to the white light LEDs technical development, white light LEDs will become a kind of very competitive new type electro source.LED as novel solid state light emitter also have start-up time short, do not have ultraviolet ray, rich color full, can full-colorly change, characteristics such as low-voltage safety, use very flexibly, can make the compact light source product of point, line, surface various forms form.

China is in big construction period at present; A large amount of new building crowds are built, and each city also has a large amount of bright lamp engineerings simultaneously, and China also is the city of an energy scarcity; How to take into account energy-conservationly and attractive in appearance, taking into account the stable of system and being easy to management becomes urgent problem.

Traditional LED light adjusting controller can only carry out simple light modulation, and function singleness can not intercom between each light adjusting controller mutually, and the composition system that more can not network realize intelligent control, and the light modulation precision is low, scintillation can occur.The Along with people's growth in the living standard, requiring of people's illumination control is increasingly high, as builds comfortable lighting environment, saves energy, raising light source life or the like.Obviously traditional light adjusting controller has not satisfied people's requirement.

Traditional LED light adjusting controller can only carry out simple light modulation, and function singleness can not intercom between each light adjusting controller mutually, and the composition system that more can not network realize intelligent control, and the light modulation precision is low, scintillation can occur.And at present on the domestic market based on bus LED illumination driving governor monopolized ABB AB for example, SIMENS company etc. basically by foreign system.Equipment price is high, and single module is moved units then up to ten thousand, and whole engineering cost is huge, on operation interface, also has language issues.These are implemented project basic unit at home, and especially the small and medium-sized project at initial stage implements to have caused certain difficulty.
